The Effects of Marijuana on Your Body When you inhale marijuana smoke into your lungs, it is quickly released into your bloodstream on its way to your brain and other organs. It takes a little longer to be absorbed when you eat or drink it. The effects of marijuana on the body are immediate. Longer-term effects may depend on how you take it, how much you take, and how often you use it. Since its use has long been illegal in the United States, large-scale studies have been difficult to manage. In recent years, the medicinal properties of marijuana are gaining acceptance in mainstream America.
